This "invention relates to punch presses and is in the nature of improvements which may be used with the machine illustrated: in 1 myapplication Serial No. 256568 filed Feb- 5 ru'ary 24th, v1928 in which I provide a magaupward extension from whichftheblanks without interrupting the operation of the machine. v In the machine offthe present invention .envelope fasteners, in the form of fibre butguard against injury to the machine in. case one or more of the fmagazlnes becomes stopped. To this end the magazinesof the illustrative machine are secured to a support frameand yieldingly held in po siti0n' t0 maintain the receiving end of the .magazlne normally against the lower endof the die.-

15' as they'are formed, 'fit'tightlyin the upper, part ofthe dies 31'.- This assists in pree venting retrograde movement of thebuttons in the maganine,'which the weight ofithe (101- I umn of punchi'ngs -in the'delivery portion'59- tendsto produce. Thehole82 in the dieflares at'83 so asto' facilitate free passageof the punchingsfrom the die to the magazine;

By anflinspection of Figure 3 it will be seen that the'dies 31' are arranged in two rows extending forerand-aft of the machine, or in other words transversely of the strip of'material 21,!andto reduce the waste of the ma" terial to amini'murn, thedies of one roware offset with reference to the dies of the'other row. The receiving portions 56 of the mag azines are accordingly arranged in two rows and the curved port1on'58 of the'said maga zines, as they reach forward extend out- -wa'rdlyfrom eachoother to the: delivery portions 59 the portions59'being-arranged in a. single row extending transversely iof gthe machine 3: inj t e Wor s, t ght angles to the rows in which magazine portions 56- are disposed. It will also be understood that the curved portions 52 of the two rows of magazines extend in opposite directions and in fan-like relation to livery portions 59. h

To separate the buttons or fasteners into bundles or stacks preparatory to their 'removal from the magazines, a tool 61, in the fform of a flat plate and adapted to act upon the stacks simultaneously is provided. Said plate has projections 85 (Figures 8, 9, 11) to i enter the slots 60 in the magazines, the projections being pointed so that they may readily be forced between the-fasteners contained in the magazines. Before the tool 61 V is pushed into the magazines wires or rods 87 are inserted through the perforations 15 of the pile of fasteners, the upper end 88 of each wire being bent to engage the upper end of the magazine to support the wire so that the lower end of each extends beyond the position or station at whiehthe too 1 51 is applied. Theextensions 85 are provided with hooks 90 which, when the tool 61is inserted, engage behind the wires 87. After the wires have been embraced by the hooks 90 the pile of fasteners in the various 1naga:'-

zines may be raised by the tool 61 to sepa-v rate them from the other fasteners 1n the magazine. The ends of the wires 87 may then be bent outwardly by tilting the tool 61 as in Figure 9. After the lower ends of the wires have been so bent the tool 61 may be removed subsequent to which the bundles of fasteners may be removed from the magazines individually and the freshly bent end of each wire 87 may then be further bent by means of a pair of pliers, or anv other suitable tool,to retain the fastener in a'pile on said wire.

To assist in inserting thetool 61 into-the magazines there are provided two forwardly extending said bars 92 servmg as guides upon which the tool may be slid into the magazines. To

assist in locating the tool 61 laterally, with reference to the magazines, the left hand end of the tool 61 is placed against'the left hand;

side plate 66 which extends above the latter at 94 as shown inrFigure l. f

- 'To assist in gauging the number of fasteners in each pile or mother words toindicate when the tool 61should be used, there i may be provided one or more indicators .95 near the upper ends of the magazines which may be located a distance above the-bars 93 corresponding to the total height of a predetermined number offasteners. It will be understood that other indicating means, such as a counter, suitably connected to and operated by the machine may be used to inform the operative when a predetermined number of'fasteners have advanced in thedelivthe single row of de bars 93 secured to-the plat-es 66.;
